Must have powers

[Half-orc Bard]

I was wondering if there was any just amazing powers for a psion or psychic warrior. Like disitagrate, I think hostile empathetic transfer is just phenomenal are there any other must haves

I like expansion. It's cheap, it's mechanically and contextually effective and it grows in power over time.

Schism and Body Adjustment.

The one Psion I've played essentially only used Deceberate. That may not have been the best choice, but my own personal opinion.

Vigor, Astral Construct, Inertial Armor, Ego Whip...
